Question 103Safety & Environmental - Assistant Engineer

The correct answer is D) all of the above. The blowers of an inert gas generation system aboard a tanker will be automatically secured if: 1) The normal water supply at the water seal is lost, as this could allow oxygen to enter the system and create an explosive atmosphere. 2) The temperature of the inert gas being delivered to the cargo tanks exceeds 150°F, as high temperatures can damage the cargo tanks and their fittings. 3) The cooling water supply to the scrubbers is lost, as this could prevent the proper cooling and cleaning of the inert gas before it is delivered to the cargo tanks. The other options are incorrect because they only address one of the three conditions that would trigger the automatic shutdown of the inert gas blowers, while the correct answer encompasses all three critical failure modes.
